> === *Description* ============================================================
> I'm working on a networking test suite that uses ksh93 scripts and libraries
pretty extensively. I've seen the following crash from ksh93 twice now I
think,
over the course of *many* test runs as I've been working on the suite. The
stack looks like this:
>
> # file core
> core: ELF 64-bit LSB core file AMD64 Version 1, from 'ksh93'
> # mdb core
> Loading modules: [ libc.so.1 ld.so.1 ]
> > ::status
> debugging core file of ksh93 (64-bit) from mathesar.East.Sun.COM
> file: /usr/bin/amd64/ksh93
> initial argv:

> This is in project bits based on the latest Nevada, 10/22/08. The project is
not making any changes to ksh93, of course, so this should be unrelated to
anything local to the project gate.

> I've attached a core file if anyone cares to investigate.
>
> Also, this isn't CR 6715496 because I don't use arrays anywhere in the main
test code where the crash has been observed.
